Abstract
The utility model discloses a spherical tile which comprises a lining tile body, wherein more than one convex spherical surface is arranged on the lining tile body; the convex spherical surfaces are arranged on the lining tile body at equal intervals; a gap is formed between every two convex spherical surfaces. The spherical tile utilizes the spherical refraction principle, disperses impact force of a medium on the lining tile body, reduces the degree of wear, and can effectively prolong the service life of the lining tile of a steel ball coal mill.
Description
Technical field
The utility model relates to a kind of spherical bush.
Background technology
Low speed coal mill tank end lining tile is the chief component of whole lining tile system, is divided into substantially two kinds of sizes, and large lining tile is divided into again and supports watt and non-support watt, little two kinds of long teeth and the short teeth that are divided into.Larger owing to changing the difficulty of lining tile during boiler operatiopn, so directly have influence on the length of coal pulverizer time between overhauls(TBO) the service life of end lining tile, have influence in other words the coal pulverizer safe operation cycle length, recondition expense number and the size of labour intensity, coal pulverizer run duration lining tile damage simultaneously can cause the situation of serious leakage powder to occur.In sum, lining tile length in service life in end is the principal element that affects coal pulverizer continuous operating time.Owing to entering at present, stove ature of coal particle is harder, and the hardness of changing some steel ball increases to 549HB by original 450HB, the hardness of lining tile is 508HB at present, and lining tile wearing and tearing are very serious, use the one-year age will the worn out phenomenon of occurrence of large-area, be difficult to meet the requirement of actual motion.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of refraction at spherical surface principle of utilizing, and the impact of decentralized medium to lining tile reduces the degree of wear, can effectively improve the spherical bush in lining tile service life of low speed coal mill.
For addressing the above problem, the utility model adopts following technical scheme:
A spherical bush, comprises lining tile body, is also provided with more than one convex sphere on described lining tile body, and described each convex sphere is equidistantly arranged on lining tile body, between described each convex sphere, is provided with spacing.
As preferably, described each convex spherical surface hill height is 5mm.
As preferably, described each convex spherical diameter is 30mm.
As preferably, described spacing is 8mm.
The beneficial effects of the utility model are: owing to being provided with set bolt, lining tile body can be fixed on corresponding device, owing to being provided with more than one convex sphere, can utilize refraction at spherical surface principle, the impact of decentralized medium to lining tile, reduce the degree of wear, thereby reach the effect in lining tile service life of improving low speed coal mill.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of spherical bush of the utility model.
Fig. 2 is the side view of a kind of spherical bush of the utility model.
The specific embodiment
Consult shown in Fig. 1-Fig. 2, a kind of spherical bush, comprises lining tile body 1, and described lining tile body 1 is provided with more than one convex sphere 2, and described each convex sphere 2 is equidistantly arranged on lining tile body 1, between described each convex sphere 2, is provided with spacing 3.
Described each convex sphere 2 heights of projection are 5mm, coordinate with corresponding device, reach best bounce-back effect.
Described each convex sphere 2 diameters are 30mm, coordinate with corresponding device, reach best bounce-back effect.
Described spacing 3 is 8mm, coordinates with corresponding device, reaches best bounce-back effect.
Original lining tile mostly is relatively even curface setting, but relatively even curface can not scatter the power being subject to, and the damage being therefore subject to is also just larger; Improved sphere lining tile one utilizes the radian head it off of hemisphere, and two can flick the media such as steel ball again to different angles, and the process flicking reduces the efficiency of impact, wearing and tearing, can form a part to the medium that soon impact will come again and stop.
Object is degree firmly, except the strength of materials with self is relevant, more important point is its profile, because convex surface can distribute along convex surface the impressed pressure being subject to come, and everywhere is stressed more even, this just allows hemispherical have very large rigidity.Smooth hemispherical can impact forces along spherical mean spread out.
During coal pulverizer operation, have countless steel balls and raw coal, pulverized coal particle impact wear lining tile, relatively even curface can not scatter the power being subject to originally, and the damage being therefore subject to is also just larger; Improved sphere lining tile one utilizes the radian head it off of hemisphere, and two can flick the media such as steel ball again to different angles, and the process flicking reduces the efficiency of impact, wearing and tearing, can form a part to the medium that soon impact will come again and stop.Be to achieve many things at one stroke.The lining tile of same material, will have a clear superiority in the service life of sphere lining tile.
According to this scheme, not only can transform coal pulverizer lining tile, this technology can also be applied to other positions in pulverized coal preparation system equipment, for example: coal pulverizer feed box; Mixer; An airduct elbow etc.
The beneficial effects of the utility model are: owing to being provided with set bolt, lining tile body can be fixed on corresponding device, owing to being provided with more than one convex sphere, can utilize refraction at spherical surface principle, the impact of decentralized medium to lining tile, reduce the degree of wear, thereby reach the effect in lining tile service life of improving low speed coal mill.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
